CORPORATION OF ILLINOIS TRANSMISSION CONTROL Application filed January 10, 1925. Serial No. 1,528.

My invention relates to new and useful improvements in speed selectors and transmission controls of the type illustrated and described in Patent No. 1,486,447, issued 'to in e March 11, 1924, and in my copending application Serial No. 1,527, filed January 10, 1925, for transmission control.

My invention is also applicable as an improved controlling means for the mechanical gear shifting device manufactured by the Cutler-Hammer Manufacturing Company of Milwaukee, Wisconsin, andapplied to the automobile manufactured by the Apperson Motor Car Company.

The principal obJects of my invention are to provide a pedal speed-change selecting device that is simple, positive, convenient, and practical in operation and construction and comparatively cheap to manufacture; to provide a single operation speed-change and Vclutch control whereby movementl of the clutch pedal operates the clutch and selects and shifts the gears; to provide a simple foot pedal, the bodily depression of which positions the parts for the selection of one'of the speed ratios; to `provide in a combined clutch and speed-selecting pedal, of the type wherein ya speed ratio is disengaged and a new speed ratio engaged during the movement of lie pedal, means to allow absolute vfreedom of selection until the time for positioning` the Vparts for the engagement'of the new speed ratio; to provide a combined clutch and speed selecting pedal that will disengage the engaged and engage a new speed on the same positive forward stroke ofv the pedal if the transmission is so designed, or permit the engagement of the new speed upon release of the pedal, if necessary; to provide a mechanism which will permit freedom of selection after the initial depression of the pedal, thus enabling a change of intention on the part of the operator; to provide manual control for cert-ain transmission positions; and to provide an indicator to show at all times the position of the selector mechanism and consequently the position of the transmission.

With these and other objects in view, my invention consists in certain novel features of construction and arrangement of parts,

hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in whichr y Figure 1 is a sidey elevational view of `my improved speed selection means.

mechanism disclosed in my Patent No.

1,486,447, issued March 11, 1924,v in whichV latter; case a cam would preferablyfbe substituted for the arm Pedal facei is .a rigid member, being grilled to prevent the operators foot'from slipping. i"

The main portion 6 of the pedal Hat and preferably in 'the form ofa pentagon. Two auxiliary faces 7 v and 8., are formedv with, but inclined down from, the main body portion 6 at the upper right and left edges, respectively.-y Openings 9 and 10 are provided in the inclined portions 7 and 8 of the pedal face. i

-Upstanding guard lugs 11 and 12. are provided on either side of the pedalface to lreep the operators footfroni slipping oft' the pedal when the foot is directed against; one of the inclined portions. Selector'l is pivotally mounted to ythe free end of pedal 1l by means of'pin 14.v xThe upper,` end of the selector is bifurcated, formingvtwo memldirect a certain speed engagebers and 16 extending in a plane at right angles to the axis yof pin 14. Members 15 and 16 terminate in upstanding lugs 17 and 18 which extend through the openings 9 and 10 inthe inclined portions of the pedal face and'in turn terminate in a plane lower than that of the main body portion 6 of the pedal face. The lower end of the selector is also bifurcated to form two spaced Aparallel members 19 and 2O whose longitudinal axes are parallel to the axis of the main body portion of selector 13. 21 Vis a fixed housing and guide substantially rectangular in cross section open at the top and bottom and slotted to vallow movement of pedal 1. This housing preferably tapers from top to bottom where a transverse sha-ft or pin 22 is mounted.

The space'between the front and rear portions of the bottom edges of this housing is just su'flicient to clear the parallel members 19and 2 0 of selector 13. A compound cam 23 is loosely mounted on shaft 22. This cam is provided with two double face portions 24 and25 and a single face portion. Eachv of the Vsides v26 and 27 ofthe single face portion provides a different operation. An arm V28 operates and is preferably formed with cam 23 asa projection of cam portion 24. A directional rod 29 is connected to arm 28. The purposeof rod 29 is to arrange speed Y change mechanism (not shown) so that effort transmitted through rod 4 will change thetransmission of power to neutral or to the ratio directed by the, operator through ro'd 29. .f

Arm 30 projects from Varm 28 at .right angles thereto and is linked to an auxiliaryk control and indicator 31 by rod 32 and arm 33. Arm 33 is fixed on shaft 34, as is the indicatorlinger 35. The indicator 31 is located within sight and easy reachof the operator; for example, inthe case of an automobile, it

'would beV preferably located on the instru-4 7 `ment board. A blade spring 36 is mounted on the back of the. indicator to engage notches 377 385 39, 40 and 41 in block 42. The block 42 is Xed to shaft 34 to rotate therewith. The engagementof .the blade spring in the notches vmay be felt by the operator during the use of theindicator as a manual lcontrol and enables the operator to feel its position at night if the dial 43 is not illuminated.

Pins 44 are fixed near the lower edge of the'inner front end of-housing21 to prevent jamming of 'the mechanism by the engage ment of moreithan one portion of the cam by the members 19 and 20 of selector 13.

The blade springsy 45 and 46 are riveted to the innerY side oftheV housing near the top andtensioned so asto-ben-d inwardly away from the housing. Y Their inward movement is limited by hooks47and 48 which' are Xed to the springs and entendthrough `openings in the housing. These bla-de'y springs are substantially VVthe width: of the housing throughout their length so that they direct Y 50 limits both thel upward and downward movement of pedal 1 so that the selector will not strike against the body of the camv on its downwardtravel, and unduly strain or bend it, and so that the members 19 and 2O of the selector are lower than the top Vof the housing 21 at the upward limit of'V its movement. l

To operate my improved speed selector, the driver before starting the engine or lother motive power which provides the drive to the transmission, directs the manual indicator finger 35 to the letter N on the dial 43.V He then places hisV foot upon the pedal face so Vas to contact with button 1T and depresses the pedal. The resultant pressure upon button 17, which can be accentuated if desired by correspondingly slightlyl tilting the foot7 pivots the selec-tor 13 upon its pin 14 Aand shifts the forked members 19 and 20 to the extreme righthand side of thel housing 21. y (See position shown in dotted lines in Figure 6.) The cam 23 has been positioned by linkage with 19 and 2O of the selector` and not'contact withy either one of these members.

Vthe manual indicator so that the surfaces 26 and 27 will be between theforled members Upondepression of the clutch pedal, the d' blade spring 46 is compressed by the selector .and acts to longitudinally align theme-Embers 19 and 20 rof the selector so that they will pass the cam in a position at right angles to the axis of the cam. During this neutralizing movementthere is no operative contactv between the cani 23 and the selector. The selector merely passes idly by without corr tacting'witli either of the surfaces 26 and-27 of the cam. 'ln this position, the directional rod 29 is not operated by the clutch pedal and selector member 13 but only by the manual i indicator. The shifting rod 4 acting with the clutch pedal 1 will now produce the neutralV position direc-ted bythe rod 29 upon depression of the clutch pedal.

To directthe parts for the engagement of l ly to ride along the inner edge of the member 19 of the selector. TWhen the cam has been turned to this position, the rod 29 attains a position that will direct the transmission mechanism "for the engagement of the first forward speed upon the .operation of rod 4. rlhe eiiective operating movement of rod 4 i-s pre'feiablyL produced during the last portion of the forward or downward movement of the clutch pedal so that the engagement ot the transmission elements is positive. This is achieved without .providing lost motion by utilizing a cam, the raised portion of which is brought to bear at the desired time.

To obtain the second -forward speed, the operators foot is placed directly upon the pedal without contact with'either of the buttons 17 or 1S. The pedal is tnen depre-ssed. The blade springs 45 and 46 direct the members 19 and 2O o'selec-tor 13 over the central por- Y tion of the cam so that the faces 25 will ride against the inner faces of these members 19 and 20. The cam will be i rotated by the selector until it is so positioned that the forked members can pass and thus produce a diderent position in the rod29 which directs the speed change mechanism for the engagement of the second forward speed upon the operative action of the rod 4.

To obtain the third forward speed, the butf i ton 18 is contacted with by the operators ioot, shifting the selector to the legit' side of the housing 21 Yand depressing spring Upon depression of the clutch pedal, the two n'iembei'sl9 and 2G of Jrhe selector are again aligned in a. position at right angles to Vthe az-:is oiv vhe cam. rlhe initial Contact of these two members bythe laces 24. The rotation ofthe cam-pra vides a new position in rod 29 which directs the transmission elements for the engagement of the third forward speed uponthe opera-A tive movement of the rod 4.

To obtainthe reverse speed, the manual in-A Y dicator must be movedto point to. the letter t on dial 48. This movement alone positions the caniand shifts the rod 29 lor reverse.

Y The operators foot is brought intov Contact with the button 17 to shift the selector to the right side of housing 21. The relative positioning of the selector and' the'v cam are now such that upon depression of the pedal, part 2O of the selecto-r will slide'idly over surface 27o" the cam (see Figure without rotating the sanie;-sai d depression of" the. pedal being necessary in order to accomplish the selected speed through shifting of rod 4.

It is to be understood that after -the. "ection of neutral position or reverse speed, it is not essential to manually move the indicator in order to directv the engagement of the iirst speed." This may also vbe done by rotating the cam 23 by Contact' with either of thev double face portions 24 and 25.v When with the camtends'to rotate the cam so that the members 19 and 2O may pass this is done and it is ldesired to enter first speed, the clutch pedal is. not fully released, but only to a point wherethe member 19 of the selector is operatively iree from the pins 44 so that it may be directed over the single face portion of the cam'.` fvVith the parts thus positioned, the operator may contact the button 17 and redepress the pedal to direct the engagement 'of irstspeed. VHowever, it is necessaryto use the manual indicator for the direction of reverse speed and the positive neutral. The notches 37, 38, 39, 40 and 41 in block 42 are spaced to provide set positions for the rod 29 bythe engage? ment of blade spring 34 therein,thus,in cooperation with the indicator'providing also maiual selection means, should'such'be desire. fr A It will be noted, 'furthermore that it 'is possible b-y the bodily removal of the selector member 13 to operate my device purely as a manual selector. In this case all of the notches in Vblock 42 are utilized to determine Y the correct position for rodl 29. f

It will be readily understood that minor changes in the form and construction-of the various parts of my improved'transmission control vmay be made and substitutel for those herein shown anddescribed, without departing from the spirit of my invention,
